“I try (to be honest). Of course, sometimes you have to say something different. But in 99 per cent of cases, I try to be honest.”

Chelsea’s appeal against a two-window transfer ban relating to recruitment of overseas players aged under 18 will be heard by FIFA on Thursday.

The Blues insisted they were “astonished” by the suspension and still aim to have that embargo overturned.

Chelsea’s legal team will attend the hearing in Zurich just hours before the Stamford Bridge men face Slavia Prague in their Europa League quarter-final first leg.

And boss Sarri insisted he will ban any talk of that hearing before the Sinobo Stadium clash against Slavia.

Asked if he would seek updates on the appeal hearing, Sarri said: “Not before the match, for sure.

“We have a club who are very careful about everything, so I don’t want to talk about this.

“We are here for the Europa League, a very important target for us, and I want my players to think only about the Europa League.”

Slavia Prague bosses believe UEFA punishments will take the shine off their “match of the decade” against Chelsea.

Three sections of Slavia’s Sinobo Stadium will be closed to fans.

Slavia were fined £32,000 by UEFA and had the one-match partial stadium closure imposed after supporters set off fireworks, threw objects onto the pitch and blocked stairways in the goalless draw with Genk on February 14.
